Technical field

The present invention relates to the equipment that filters and/or regulate and/or purify for to the fluid such as water etc., more specifically, the equipment that relates to the pressurized vessel that uses the filter cylinder be kept for filtration and/or adjusting and/or cleansing fluid (such as water), pourable medium etc.The present invention also relates to various fuid distribution systems, such as the water distribution system of quoting of aircraft.

Background technology

Aircraft tap water purposes---for comfortable voyage, especially can continue 20 or modern times of flight in more hours, very large, long haul aircraft on, enough water particularly importants.Usually, during flying, water is assigned to kitchen, lavatory and the tap water outlet of aircraft, the water for preparing F﹠B to supply drinking water to the passenger, to be provided for and the water that is provided for Personal hygiene (for example, wash one's face and wash one's hands, cleaning of teeth etc.).In a week, aircraft has been built up the thousands of passengers by the diversity of settings of commercial passenger plane usually, comprises baby, child, Disabled persons, ill people and other crowds of possibility.Passenger and steward promote the microbial reproduction on aircraft, and must take professional preventive measures, with the possibility of avoiding bacterium, virus, pathogenic agent and other microorganisms to propagate between the passenger by water distribution system.In addition, water is fed into aircraft from many places, and the taste of water and health product matter alter a great deal.Except with the effective airborne tap water micro-filter/water purifier of water end (W.E.), the main health Avoid of directed toward bacteria and virus will water store and distribution system in keep enough chlorine remnants, be preferably free state chlorine.In addition, effectively airbornely remove reliably the pathogenic agent Etiological of waterborne disease (world wide in) with water end (W.E.) tap water micro-filter/water purifier, such as the giardia lamblia stiles and the Cryptosporidium that not controlled by chlorination.

Water dispenser on aircraft and management---the water distribution system on aircraft generally includes the water storage tank of supply centralized distribution pipeline, and this centralized distribution pipeline has various arms or the branch road that extends to each position of whole aircraft from the centralized distribution pipeline.For example, during flying, as required by water distribution system with water dispenser to kitchen, lavatory and other position, be used for carrying out the F﹠B preparation, and be used for Personal hygiene.The kitchen comprises many " service points ", such as coffee machine, hot water boiler and tap water outlet.Similarly, the lavatory generally includes tap water outlet, and can be used for washing one's face and wash one's hands, cleaning of teeth and short-term individual medication.Have many chances of aircraft potable water system/supply microbial contamination, though on being loaded onto aircraft the time be hygienic safety be also like this.

Usually, each water filter/water purifier unit that includes housing pressure container and filtration/water purification cartridge is installed in kitchen or lavatory or near it, as the part of aircraft water distribution system, in order to improve the quality that is used for consuming and being used for the water of F﹠B preparation.Water purifier (water filter/have the water purifier of water purification element) must be through independent authentication, to satisfy U.S. EPAAbout bacterium, virus and pathogenic agent Microorganism water purification device guidance standard rules(EPA Guide Standard Protocol for Microbiological Purifier).The Structured Matrix that General Ecology sells ^TMWater purifier also provides fabulous filtration.Strainer is such as the Structured Matrix of General Ecology company ^TMMicro-filter or simple, particulate or coarse grained carbon and/or settling system can be by perfect, but these strainers be authenticated to be satisfied The microorganism of U.S. EPA Water purifier guidance standard rulesBefore, can not be called as legally the microorganism water purification device.Space between kitchen and lavatory is expensive and extremely limited.Therefore, must " allowably " water filter/water purifier unit be installed, usually be installed in the position that is difficult to contact, after these positions are in other equipment and bulkhead that are easier to contact usually.

The health rules---the microorganism that may be correlated with is pathogenetic bacteria, pathogenic agent and virus.Anti-chlorine pathogenic agent such as Cryptosporidium, needs special consideration and sfgd., such as providing with water end (W.E.) water filter/water purifier unit (for example, along the water purifier of aircraft water distribution system, to remove pathogenic agent from the water that flows therein).This water filter/water purifier unit is also removed bacterium, virus and other microorganisms from the water that flows therein.In addition, the problem of propagating by water system and breeding in aircraft tap water distribution system in order to overcome virus and bacterium, airline attempts usually to guarantee that the enough chlorine in the aircraft water supply system is residual.Even so, also must regularly to aircraft water distribution system " sterilization ", usually embathe more than 2 hours with high concentration cl solution (100ppm).Before this sterilization process, this sterilization process need consuming time and arduously on whole aircraft the water filter/water purifier unit from be arranged on kitchen, water receiver and lavatory pull down filtration/purifying tube.After pulling down filter cylinder, must reinstall pressurized vessel, to allow sterilized solution by the seepage of distributing and prevent the sterilized solution of this highly corrosive and oxidisability fully of water distribution system at two hours between the sterilization soak period.

Because following at least two kinds of reasons require to pull down filter cylinder: 1) because high concentration cl is harmful to great majority filtration/clean cartridge, and 2) more importantly, because microorganism may be ensconced in the gap and defective of sealing face intersection of water filter/water purifier unit (ideal position of biofilm formation), this impairs the validity of sterilizing process, therefore allows the breeding again of distribution system.Even think that sterilization effectively, but the revenue losses of usually stopping work and causing due to higher cost and the aircraft during the sterilization process of sterilization process, so frequently do not carry out sterilization---may every six months once, or " inspections of A level " or the longer service intervals when other are safeguarded in execution carry out with easily.

Operate before chlorine rinses and soaks the laggard trade in two hours, namely again open pressurized vessel and same filter cylinder (the perhaps new filter cylinder of replacing) is installed.With the whole aircraft water distribution system of tap water cleaning down, with the sterilized solution of the high concentration of thorough removing.Sterilization may need several hours to aircraft, causes average cost up to hundreds of dollars of per unit.Sterilization more effective, lower cost will allow more frequent sterilization and may provide higher-quality tap water with better economy.

System drainage and additional---during the shut-down period (such as night) under cold climate, water must be discharged from aircraft.The U.S. EPA code requirement that proposes is more continually to water storage tank draining and filling water storage tank, to make great efforts to improve quality and the security of aircraft tap water.Draining and filling system need to be in device location " vacuum eliminations ", allowing suitably releasing water, and allow " ventilation " to allow the air effusion, in order to guarantee the suitable function of strainer, water purifier and other equipment.Although up-to-date strainer/water purifier unit comprises that automatic vacuum is eliminated and ventilation, most of aircrafts unit requirement manual activation, this causes inadequate draining and water-filling usually.

Similarly, under the U.S. EPA standard that proposes, due to " shut-down " revenue losses that is difficult to touch water filter/water purifier unit and aircraft, sometimes ignored in the past touch and actuate manual ventilation and vacuum are eliminated and may be become the obvious more project of high maintenance cost.

Microorganism growth---even regularly sterilization, bacterium also may be in each arm (branch road) breedings of water distribution system.Bacterium is Fast-propagation exponentially, and is sometimes double with regard to quantity in approximate 16 minutes.Therefore, in the water that will consume, especially in the strainer that is used for removing chlorine, undesirable taste and smell of installing inadequately/safeguarding/water purifier downstream, a small amount of bacterium can reach infectivity concentration fast.In addition, be arranged on the longer distribution pipeline that exceeds expectation that usually need to arrive concrete use water spot (for example, water is from the position of water distribution system distribution) along the water filter/water purifier unit in half long-range distance and position of water distribution system.These distribution pipelines provide makes that the water that before purified is rotten in the accident in water filter/purifier unit downstream by occurring in this distribution pipeline, the unnecessary chance of the multiplication of short-term bacterium or biofilm formation/come off and pollute.

Described protrusion is around the neighboring of the described dish of described flapper valve, the fluid that described protrusion causes in the described first channel of described pressurized vessel being back to from the downstream of described protrusion described protrusion upstream moves the second side of the described dish of crossing described protrusion and moving to described flapper valve, thereby promote described dish and contact described first channel with the closed described pressurized vessel at described flapper valve place with the inwall of described pressurized vessel, to reduce/to stop fluid from the described backflow that enters flow port of described pressurized vessel.

18. pressurized vessel according to claim 16 also comprises:

Annular element, described annular element are positioned between the inwall of described device for filtration and/or adjusting and/or cleansing fluid and described pressurized vessel and are adjacent with the inwall of described device for filtration and/or adjusting and/or cleansing fluid and described pressurized vessel,

Described annular element has outward extending elastic flange, and described elastic flange engages the inwall of described pressurized vessel and as vibroshock, avoids damage with the described device for filtration and/or adjusting and/or cleansing fluid of protection when described pressurized vessel drops.

19. pressurized vessel according to claim 16,

Described pressurized vessel comprises compressible post, and described compressible post is arranged in described pressurized vessel and is substantially surrounded by described device for filtration and/or adjusting and/or cleansing fluid, is used for allowing may expanding of described fluid,

Described compressible post comprises the enclosing foam unit that contains air, and

Described compressible post is freezing and protect when expanding described pressurized vessel and/or described device for filtration and/or adjusting and/or cleansing fluid not to sustain damage because fluid is freezing in described pressurized vessel at described fluid by the space that is provided for fluid expansion; freezing along with described fluid, described fluid expansion are in described compressible post and compress described compressible post.
